I went on a weekday morning and it was quiet, with almost no wait time. It seemed like there were the most kids around lunchtime. There's a rock climbing-like activity, but you can't do it if you're wearing Crocs, so it's best to wear sneakers. Inside, there are restaurants serving Japanese food (tonkatsu, rice bowls), Subway sandwiches, and burgers and chicken. The prices are theme park level, a little on the expensive side.
